Feature Keys

Line Keys

The line keys, along the display, can be programmed to allow you to select which line you wish to use to make a call (if you use your phone with more than one account).

Under the Phone tab, select which extension each line key should correspond to. You can give each a short name that will appear alongside the button on the display.

Or if you have buttons spare, they can be set up to be BLF + speed dial + call pickup buttons.

This allows you to monitor the state of another extension (if it is ringing, busy or available), quickly dial that extension, or pick up an extension that is ringing (and there is nobody there).

  1. First, click the advanced button on the top-right.
  2. Go to the Attendant Console tab
    • Set Server Type to Asterisk
    • Set Attendant Console Call Pickup Code to **#
  3. Go to the Phone tab
    • For each button you wish to use as a BLF+SD+CP key, set Extension to Disabled
    • Type in something short yet relevant into the Short Name field, such as the person's name
    • In Extended Function put in: fnc=sd+blf+cp;sub=XXXX@$PROXY
      XXXX is the extension you wish to monitor
    • Alternatively, for Speed Dial only to an external number, simply put in: fnc=sd;ext=XXXXXXXXXXX@$PROXY
      Where XXXXXXXXXXX is the number to dial.
  4. When the monitored extension is available, it shows green. Red when on a call or busy. Blinking red when ringing. Orange if there is an error in the syntax.
  5. It is highly recommended to remove any conflicting Vertical Service Activation Codes in the Regional tab. Simply clear them out and click Submit All Changes.
  6. Please note that at least 1 line key is required for the actual line, otherwise your phone will be unable to function properly.

Voicemail

To program the Voicemail key to dial your voicemail, go to the Phone tab, and in the Voice Mail Number field put in *97

Additional Settings

These are optional settings, but are highly recommended to get the best experience out of your phone.

Set Time Servers

In System tab, under Optional Network Configuration

Use the above as an example as your system administrator may be able to provide you with your company's internal NTP servers.

In Regional tab, under Miscellaneous

Troubleshooting

If registration is failing, check over the settings entered above.

Ensure SIP ALG is disabled on your router. See this page for further information.

If the Status page shows timeout, check over your firewall settings.

If you are still having trouble registering, contact SureVoIP Technical Support.
